Managing navigation of multiple content flows in an electronic publication

Abstract

A method and system to maintain, in a data store associated with a device, first content of an electronic publication, second content of the electronic publication, and mapping information enabling navigation between a first navigational structure of the first content and a second navigational structure of the second content. In response to one or more first indications, the first navigational structure of the first content is navigated. The method and system receive, via an access point corresponding to a first location of the first navigational structure, an indication to access the second navigational structure. Using the mapping information, a second location within the second navigational structure is determined in view of the first location of the first navigational structure. The method and system generate, via an interface of the device, a display comprising a portion of the second content corresponding to the second location within the second navigational structure.
